겨울철 SET<SUP>*</SUP>의 실외 환경 적용 가능성 검토
박희욱(Hee-Ouk Park) 한국생활환경학회 2000 한국생활환경학회지 Vol.7 No.2
The thermal indices which show the relation between human thermal sensation and surrounding outdoor climatic conditions is not made so clear as in the indoor one. In the paper, the applicability of SET<SUP>*</SUP> to the outdoor climatic environment in the winter was examined by the experiment of thermal sensation from physiogical and psychological view point. The result are as follows. SET*<SUP></SUP> upper 19℃ and MST upper 31.4℃ are considered to be the comfort zone in the outdoor environment. The thermal sensation was more influenced by air velocity than by solar radiation.

Purpose of this study is first to show the effects of vertical air temperature differences on thermal comfort and physiological responses, and second to examine the acceptable vertical air temperature differences. In this experiments, 12 subjects (6 males and 6 females) were exposed at 12 test conditions. The subjects voted each 10 min, about his thermal feeling, and 7 skin surface temperature, the air temperature were measured every 20 second. From this experiments, it was found that the upper part temperature affects the thermal sensation more strongly than lower part temperature. In winter, the acceptable temperature differences drawn by this study are 3℃ in the case that the upper part temperature is higher than the lower part temperature.

The purposes of this study are to investigate the correlation between SET*(PMV) and thermal sensation of Koreans through subjective judgement and to find out thermal comfort zone of Koreans indicated by SET*(PMV) as compared with ASHRAE Standard 55-74 comfort zone. In this paper, results of one series of experiments conducted in winter season are reported. The subjects wore standard uniforms and remained sedentary throughout the experiment. Skin temperature at 3 sites was measured. Thermal sensation and comfort sensation were voted every 15 minutes. The thermal sensation vote was consisted of a seven-point scale in which -3 was cold, -2=cool, -1=slightly cool, 0=neutral, +1=slightly warm, +2=warm, +3=hot. And the comfort sensation vote consisted of a four-point scale in which 0 was comfortable, +1=slightly comfortable, +2=uncomfortable, +3=very uncomfortable. The results in the winter subjective experiment were follows. 1) SET*(TSV=0) of young subjects was 25.5℃. 2) The thermally neutral zone of young subjects was 24.2∼26.8℃(SET*). This zone included ASHRAE comfort zone and was shown to extend to higher range. Part I : Analysis of Subjective Judgement in Winter Experiment

최근 경제 발전과 인구증가에 따라 대형 및 고층건물의 수가 증가하고 있어, 건물의 냉난방, 조명, 급탕, 수송, 통신, 방재 등 각종 설비의 발달과 함께 이들이 사용하는 에너지의 양도 막대할 뿐만 아니라 앞으로도 계속 증가 추세에 있으나, 에너지 소비량과 소비요인에 대한 정확한 자료와 연구가 부족한 실정이다. 따라서 본 연구에서는 에너지 다소비 건물인 종합병원을 대상으로 에너지 소비와 운전실태에 관한 현장조사를 실시하여 병원의 설비계획시 기초자료를 제공하고자 한다. Recently, as the number of large buildings is on the increase and the various mechanical equipments for heating and cooling, illumination, hot water supply, transportation, communication, and disaster protection system in the buildings are advancing, the energy consumption is on the increase as well. It will be very important to understand how and how much energy is to be consumed in a building, because there are not many stastististics and studies on the energy consumption in building. The aim of this paper is to suggest basic data for performing the energy conservation and establishing the standard of the energy consumption in future through undrstanding the actual condition of the energy consumption in existing General hospital.
